Dual Modulating Combustion Systems
The water heater is provided with two independent combustion systems. Each combustion system has a separate control that
modulates burner output based on measurements taken by water temperature sensors located within the upper and lower portions of
the storage tank, efficiently regulating burner output to match system demand. These systems increase efficiency and allow for
substantial fuel savings.
Gas Valve
The gas valve senses suction from the blower, allowing gas to flow only if the gas valve is energized and combustion air is flowing.
Upper Supply Tank Sensor
This sensor monitors the upper portion water temperature (system supply) of the water heater. The control module adjusts the burner
firing rate so the outlet water temperature meets the set point.
Lower Return Tank Sensor
This sensor monitors the lower portion of the water heater inlet water temperature (system return). The control module reduces or
increases input, depending on how close the water temperature is to the outlet water temperature set point.
Control
The integ
rated control system monitors upper and lower water temperature and regulates fan speed to regulate the unit’s energy
output. This allows the unit to deliver the required amount of heated energy and nothing more.
Burner
Constructed of high grade stainless steel, the burner uses pre-mixed air and gas and provides a wide range of firing rates.
Condensate Drain Connection
This is a condensing high efficiency water heater, and therefore has a condensate removal system. Condensate is nothing more than
water vapor, derived from combustion products and similar to that produced by an automobile when it is initially started. It is very
important that the condensate line slopes away from the water heater and down to a suitable drain.
If the condensate outlet on the heater is lower than the drain, you must use a condensate removal pump (kit p/n 554200 available from
HTP.) In addition, local authorities may require a condensate neutralizer to neutralize the condensate. Condensate neutralizers are
made up of lime crystals, marble or phosphate chips. Neutralizers can be installed in the field by the installer and purchased from HTP
(p/n 7450P-212).
It is also very important not to expose the condensate line to freezing temperatures or any type of blockage. Plastic tubing must be the
only material used for the condensate line. Steel, brass, copper or other materials will be subject to corrosion or deterioration. A second
vent may be necessary to prevent condensate line vacuum lock on a long horizontal run. Also, an increase in pipe size may be
necessary to allow condensate to drain properly. Support of the condensate line may be necessary to avoid blockage of the condensate
flow.
Spark Ignition
The burner flame is ignited by applying high voltage to the system spark electrode. This causes a spark from electrode to ground.
